Cisco 7507 Overview

The Cisco 7507 supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and any combination of available electrical interfaces and media.

Network interfaces reside on interface processors that provide a direct connection between the two CyBuses in the Cisco 7507 and your external networks. The Cisco 7507 has seven slots: interface processor slots 0 and 1, Route Switch Processor (RSP2, RSP4/4+, RSP8, or RSP16) slots 2 and 3, and interface processor slots 4 through 6. The Cisco 7507 supports 5 VIPs, one for each interface processor slot.

There are bays for up to two AC-input or DC-input power supplies. The chassis will operate with one power supply. Although a second power supply is not required, it allows load sharing and increased system availability.

Caution Because of agency compliance and safety issues, mixing AC-input and DC-input power supplies in the same Cisco 7507 is not a supported configuration and should not be attempted. Doing so might cause damage.

The Cisco 7507 front panel, shown in Figure 1-4, contains three status indicators and two removable panels for access to the internal components. The three light emitting diodes (LEDs) on the front panel indicate normal system operation and the currently active power supplies. On the back of the router, a normal LED on the RSP and LEDs on the power supplies indicate the same status.
